To all who/)L it ntay concern:

Be it known that l, ADAM J. ScnonNBoaN, a citizen of the United States,residing at Greenleaf, .in the county of Vashington and State of Kansas,have invented certain new and useful Improvements in Telescopes, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to an improvement in hand grips, moreparticularly to that type of hand grips known as telescopes.

The object of the present invention is the provision of a device of thischaracter, the telescoping sections of which may be locked in variouspositions of adjustment so that they may be readily disengaged, withoutthe use of straps or similar fastening means.

Other objects of the invention will be apparent from the detaileddescription hereinafter, when read in connection with the accompanyingdrawings forming part hereof, wherein a preferable embodiment of myinvention is shown and wherein like numerals of reference refer tosimilar parts in the several views.

ln the drawings, Figure l is a longitudinal section of my improvedtelescope, and Fig. 2 is an end view thereof. i

Referring now more particularly to the drawings, A and B designate theupper and lower sections of the telescope, which are preferably formedof metal, and which telescope in the usual manner, the upper section Asnugly fitting over the lower section B. Secured to the top of the uppersection A is a handle a of any suitable construction. T he end walls ofthe lower section B are each provided medially thereof with a verticalrow of apertures b therein. Secured to the inner faces of the end wallsof the lower section B and covering the apertures l) therein are thevertically disposed arched plates t. The lower ends of the shields orplates t are preferably closed to prevent any extraneous .matter fromworking into the telescope through the apertures l). The end walls ofthe upper section A are provided medially thereof with spring catches7which are designed to engage with the apertures l) in the end walls ofthe lower section B to lock the two sections together.

T he spring catches, above referred to, each comprise a strip of springmetal, which is rigidly secured at its upper end to the end wall of theupper section A of the telescope, and

1 which is provided adjacent the rear end thereof with an inwardly bentshouldered portion c which normally projects through an aperture a inthe end wall of the upper section.

The shouldered portions c of the spring catches C are formed by bendingthe strip of which the catch is made inwardly at an abrupt angle andthen bending the same outwardly, so that the lower-.end thereof willstand away from the end wall of the upper section A and constitute ahandle for manipulating the catch to withdraw the same from engagementwith the apertures l). The shouldered portions of the catches C are sofashioned that the lower faces thereof are beveled while the upper facesthereof project inwardly at substantially right angles from the endwalls of the upper section A, so that when the upper section is loweredupon the lower section, the beveled portions of the catches C willpermit the downward movement of the upper section to the desired eX-tent, but the sections cannot be separated until the hand pieces of thecatches are manipulated to withdraw the shouldered portions c thereoffrom engagement with the apertures l) in the lower section B.

From this construction it 'will be apparent that in use the lowersection is lilled and the upper section is placed thereover and moveddownwardly as far as possible, the catches C engaging with one set ofthe apertures b in the lower section B and automatically locking thesections together. The shields ln serve to prevent the contents of thegrip from interfering with the operation of the catches.

Secured to the end walls of the upper section A and extending across theapertures a/ therein are bars e2, wthich are adapted to contact with theinwardly bent shouldered portions c of the catches C to limit theoutward movement thereof.

l do not desire to limit myself to the precise form and constructionshown in the drawings, as it is obvious that many minor changes may bemade within the scope ofthe appended claims without departing from theinvention as defined in said claims.

llaving thus described the invention, what is claimed is z l. In adevice of the character described, a lower section having a plurality ofvertically disposed apertures in the end walls thereof, verticallydisposed shields closed at their IOO IIO

lower ends secured to the inner faces of said end walls and covering theapertures therein, an upper section telescoping with said lower sectionand provided with catches coperating with the apertures in the lowersection.

2. In a device of the character described, a section having a pluralityof vertically disposed apertures in the end walls thereof, a secondsection telescoping with said iirst mentioned section and provided withopenings in the end walls thereof, spring catches secured to the endWalls of said second section and provided with inwardly bent shoulderedportions projecting through the openings therein said shoulderedportions being arranged to co-operate with the apertures in the endwalls of said first mentioned section when the sections are assembled,and bars secured across the openings in the end walls of saidsecondsection, said bars being adaptedto contact with the inwardly bentshouldered portions of the catches to limit the movement thereof. l

3. In a device of the character described, a section provided withrecesses in the end walls thereof, a 'second section telescoped withsaid first mentioned section and provided with openings in the end wallsthereof, spring plates secured at their upper ends to the exterior ofthe end walls of said section and provided vwith inwardly bent portionsprojecting through the apertures therein, the lower ends of said springplates extending outwardly to constitute operating portions.

In testimony whereof I aiiiX my signature in presence of two witnesses.
